NOW L-Arginine 500 MG * 100

NOW L-Arginine 500 MG is a food supplement based on Amino Acid L-Arginine.

• Arginine is a conditionally essential basic amino acid involved primarily in urea metabolism and excretion, as well as in DNA synthesis and protein production.
• It is an important precursor of nitric oxide (NO) and thus plays a role in the dilation of blood vessels.

• Take 2 capsules twice daily as needed. 
• Take between meals or at bedtime with at least 8 oz. of water or juice to facilitate absorption.
